SPINNING AND TWISTING MACHINE. Application filed June 3, 1925. Serial No. 34,556.

- This invention relates to an improvement ing uprising from a bracket 11 fixed to in spinning and twisting machines and has the spindle rail 1 of the machine by means for its object to provide a novel means of of a bolt 12 and nut 13.

The spindle s'tep'and spindle rail and having a bearing 27 in the bolster isdenot ed by 5 and it is suitably bracket 11. The upper end of the rod 25 is 50 supported in the usual manner a spindle bevelled as s own at 28, which bevel porbase 6. spindle base 6is provided with tion coa'cts with an inclined surface of a an upright 7 having a lateral directed arm lateralarm 29. As the rod is moved upi and hub 8 carrying 2. depending pivot pin 9, wardly the bevel face 28 will ride on the which pivot pin is inserted axially in a bearinclined surface and arcuately move the arm adjust brake shoe- -ment of the whirl uprising therefrom, a

and hub 8, pivot pin- 9, upright? and spindle base 6, which movement swings the whirl 3 out of engagement with the belt and into contact with the brake 3 away from the brake shoe 23 iscontrolled by the bevel face 28 of the rod 25 moving downwardly on ,the inclined surface of the lateral arm 29, and the coaction of the spring 18 on the bearing 10 with the lug 19 and upright 7.

From the foregoing description it will be seen that I have provided a mounting which obviates the necessity-of adjusting the spindle and its support with respect to the driving belt and that it is only necessary to the brake. shoe to'meet the outward movement of the whirl away from the belt.

This feature also eliminates the usual necessary adjustment required of the vertically reciprocating rod 25 of the stop motion mechanism, wit-h respect to the lateral arm 29, since the rod may be given a movementto swing the spindle base, and the brought into operative position with the whirl and permanently secured in the hub 21 onthe arm 20 uprising from the bracket 11.

,It will also be seen that I have provided a mounting which may be readily applied to the spindle rail of a spinning an twisting-machine, now in common use, without interfering in any way with the other mechanism of the machine. It will also be understood that this mounting is very simple and compact and applicable to various forms of spinners.

It is obvious thatvarious changes may be resorted to in the form, construction an arrangement of the several parts without departing from the spirit and scope of my invention; and hence, I do not intend to be limited to the details herein shown and escribed except as they maybe included 1nv the claims.

What I claim is 2-- machine, the spindle rail, spindle driving belt, the spindle whirl,

fixed to said rail having a bearing spindle base for supthe spindle Whlll mounted .to 05011- late in saidbearing and yieldingly held in contact with the belt, a brake-shoe carrie by the bracket in position to be engaged by the whirl in its movement away from the belt, and wvertically movable sto motion rod journaled in the bracket and having, a cam engagement with the. automatically swinging the the belt into engagement with the brake.

2. In a spinning machine, the spindle rail, the spindle driving belt, the spindle whirl, a bracketfixed to said rail having a bearing 1.

The move-- stop motion rod journaled common base for brake shoe whirl away from contact with the belt, a brake shoe carried by the bracket in position to be engage by the whirl in its movement away from the belt, said brake shoe being longitudinally adjustable on the bracket toward and away from the whirl, and a vertically movable on the bracket and having a cam engagement with spindle base for automatically swinging t e whirl away from the belt into engagement with the brake.

3. In a spinning the spindle driving a bracket fixed to said and a bearing uprising therefrom, base for supporting the spindle whirl mounted to oscillate in said bearing and yieldingly held in contact with the belt, and a brake shoe carried by the arm in position to be engaged by the whirl in its movement away from the belt.
